You'll need to do a little more research than that Dave! Not least as it will depend massively on what kit you get and how much work you need to do to it to fit your own body shape.
I'd suggest reading through some of the many build threads on here or whitearmor as a starting point to get an idea of what to expect.
Then once you've decided on a kit, start up your own build thread and start asking any questions you still have at that point.
Remember, first rule of MEPD club (and any other detachment) research, research research.
Good luck bud!
